Application filed May 2,

This invention relates to lip turning machines. As herein shown the invention is embodied in a machine which 18 particularly adapted for operating upon outsoles for Me- Kay sewed shoes although in some aspects the invention is not: necessarily limited to such use but may advantageously be employed to operate upon soles of other types.

The outsole for a McKay sewed shoe is channeled alon the margin of its tread face and the lip or flap formed by the Channeling operation must be raised to open the. channel for the reception of stitches or other fastening means by which the soleis to be secured to the shoe. In order to insure that the groove which is usually provided at the base of the channel lip shall be effectively exposed for the reception of the stitches and further to insure that the channel flap, after being raised, shall not interefere with the effective operation of the stitching devices, it is usually considered desirable to have the lip turned over against the face of the sole and flattened out or set sufficiently to insure that it will not "become displaced during such stacking and handling of the sole as may occur after-the channel has been opened and before the stitching operation takes place. One objectof the present invention is to provide improved lip turning means foropcrating upon a lip after it has been prelimiarily raised somewhat above the plane of a sole, to turn the raised lip over toward the face of the sole more effectively and with greater uniformity of results upon solesof different styles than in m chines heretofore employed for thispurpose and also to turn the lip in a manner to insure against possible injury to the lip while it is being. turned.

flith this object in view, one feature of the invention consists in the combination, with means for continuously feeding a lipped sole, of means for exerting a wiping action upon the moving lip at right angles'to the length of the lip to turn the lip over toward the face of the sole. The wiping means herein shown and described comprises a plurality of yielding wiping members which are distributed around the periphery of a driven wheel and which are mounted insuch a manner that while the wheel is rotating each wiping mem- JERSEY, A CORPORATION OF LIP-TURNING MACHINE.

The Wheel is further so arranged, relatively to the preliminarily raised'lip of av sole which is presented thereto, that rotation ofthe wheel will cause the wiping members yieldingly to engage the lip'in succession, each member delivering a hammer-like blow 'substantially at the base of the lip and thereafter wiping yie'ldingly across the lip substantially in a direction at right angles to the edge'of the work and to the direction of work feed.' This combined beating and wiping act-ionresults in effectively breaking down the resistance of the lip and causes it to' be turned easily and effectively set in the desired position in a manner in simulation of well-known hand methods of turning a lip which involve pounding the lip by means of a s'hoema'kefiis hammer. To insure that the direction ofthe wiping movement shallbe maintained at right angles to the length of the lip while the sole s belng advanced continuously at a sub stantial rate of speed, and also to avoid possible injury to thelip and interference with the feed of the work such as would tend to 1 slow up its advance throughthe machine, the

lip turning means is so organized and 0p erated that not only are the wiping members caused to move transversely across the lip but they are also rendered capable of ino'ving bodily in the direction of work feed as they travel across the lip. Thus; the wiping members are enabled to partake of the advancing movement of thelip While they are in c n gagement therewith and as aresult the feed of the sole is not retarded to any appreciable extent by the .wiping action although the wip. ing members engage the lip in rapid succession. v p

In the illustratedembodiment of the inven tion the movement of the wiping membersin the direction of feed is provided for by mounting them with provision for end play between disk-like members constituting the opposite sides of the Wipingwheel' and each wiping member is acted upon by alight spring the member into normal position in the plane of rotation of the other wiping members. Not only are the w1ping members adapted to-yield as above described but they are made in the over the-lip instead of wiping across it in case the lip offers unusual resistance to turning. The wiping members are also capable of tilting or angular-1y adjusting themselves lengtlr wise of the lip to accommodate irregularities of lengthwise contour of the lip. The yieldlower feed roll is made of very small diameter ing character of the hammer-like blows" and subsequentwi ping actions ofthewiping members enable them to adapt themselves readily for operation upon soles which 'dilfer in thickness and insure against tearing or otherwiseinjuring the materialoperated upon.

Another object ofthe invention is to provide improved means to insure that the work shall be adequately supported and positively fed while the up turning means is operating 2 thereon. I

To this end and in accordance with a tun ther feature of the invention, the feeding means, comprises teed wheelsrotatable about parallel axes and arringed to "feed a sole'by engagement with opposite sides of the sole margin in the planeof rotation of the lip turning device. As herein shown, the feeding means con'iprises'afeed roll arranged with its axis at an angle to the axis or the lip turning device, the periphery of the feed,rollbeing beveled or transversely inclined with respect to itsaxis, and a second feed'roll also having abeveled periphery for engaging the oppo- SllJB SlClG of the sole marg n and co-operating with the first feed roll firmly to gripthesole and to feed it past the lipturning device. Thefeed roll which engagesthe margin at the lipped side of the sole is cupped or recessed to receive aportion of the periphery of the lip turning device, thus enabling said teed rollto be located closer to the axis otthe lip turning device to insure feeding engagement with the sole margin at the base of the lip or,

V in other words, in a region closely adjacent to thepoint of operative engagement oi said de- Vice with the work.- T lie feed rolls are adaptedto engage a substantial width o1"v the sole oi the peripheries of the feed rolls are such that the'sole' margin is gripped less tightly along its outer thanalongits inner portions thereof, thus enabling the sole to be swung readily-to maintain'operative engagement or the lip turning device with the lip along the curved portions otthe sole margin without undue frictional'rubbing or twisting of the sole over the feed rolls, and further iijisuring against any tendencyor". the sole to ride out from the grip of the rolls as itis being fed. Furthermore, the angle of bevel of the lower feed rollissuch as to insure against any tendency of the edges of the roll to dig into the face of the sole as the abruptly bent portion at the junction of the shank and torepart passes between the feed rolls. Thus, not only is injury to avoid any possibility of breaking down or flattenin out the more or less shar an le between the shank and forepart of the sole.

The invention further consists in the features. of construction andcombinations and a *rangeinents of parts hereinafter described and claimed theadv'antages of which will be obvious to those skilled in the art.

As shown in the drawings the machine com? prises in general an upper feed roll 10 and a lower feed roll 12 which co-operate to grip the margin or feather of a sole; a plow l lgtor preliminarily raisingthe channel lip; a lip turning wheel 16 for turning the raised lip over toward the face or the sole; a frame or head 18 upon which the above-mentioned parts are mounted; and a horizontal main shaft 20 which is journaled in the head 18 and is connected to drive the teed-rolls and the lip turning wheel through driving mechanism carried by the head 18. 7 p

The main drivingshatt 2,0 is provided at one end with the usual 'fastand loose pulleys 22 and 24c and is'connected with an inclined V shait 26, which carries the upper ieedroll.

- on said shafts respectively.

lower feed roll 12 is carried by a shaft 32 which is mounted in parallel relation with the shaft 26 and is driven from the latter by 42 and the lip turning wheel is carried by a shaft 52 which is parallel to the shaft 46 and is driven from the latter through intermeshing spur gears 54 and 56 on said shafts.

The upper and lower feed rolls 10 and 12 are provided with oppositely beveled faces which are arranged to grip the work and to support it with the portion which is to be operated upon disposed in a substantially horizontal plane. The upper feed roll is adapted to engage the upper side of the feather or marginal portion of the sole which lies beneath the channel lip, while the lower feed roll is arranged to engage the unlipped side of the sole margin directly beneath the portion engaged by the upper roll. The work-engaging faces of both feed rolls are knurled or roughened sufficiently to secure eilective feeding engagement with the work without unduly marring the surface thereof.

Inasmuch as the lip turning wheel is arranged to wipe transversely across the lip of the sole, as her in described, itnecessarily follows that only a comparatively narrow space will be left between the periphery of the lip turning wheel and the feather or margin of the sole for the operation of feeding means upon the upper side of the feather.

In the illustrated machine, however, the inclination of the feed roll shafts is such that by employing feed rolls beveled as herein described the sole margin may be firmly gripped and the sole positively and reliably fed by co-operating feed wheels which may be arranged to engage the sole in the plane of rotation of the lip turning wheel without interfering with the movement of the latter.

Further t6 insure that the upper feed wheel shall. engage the sole margin at the base of the lip the upper side of said feed wheel is recessed to receive a portion of the periphery of the lip turning wheel and thus to permit the work-engaging face of the upper feed wheel to be located closer to the axis of the than along the outer margin of the feather. This construction causes the sole to be securely held against any tendency of its marginalportion to ride edgewise out froinbetween the feed rolls and therefore insures'engagement of the rolls with thesole practically, throughout the full width of the rolls at all times. Any tendency ofthe lower feed roll to throw the sole out, on account of the fact that the greatest diameter of the bevel faces.

of said roll engages the outer edge of the sole margin, is counteracted by having the upper feed roll oppositely beveled so that the great est diameter of its work-engaging face engages the inner portion of the feather. By reason. of this construction a balanced feed is secured with respect to any tendency of the feed rolls to produce widthwi'se movement of the feather relatively thereto.

Inasmuch as the feed rolls are maintained,

in engagement with the full width of the':

feather throughout LllB operations upon the 7 shoe, the upper feed roll will be held at all times against the base of the lip and thus it may be relied upon to perform a guiding function taking the place of the usual edge so that use of the latter maybe dispensed with. The s ight difference in inclination of the bevel faces of the feed'rolls at their points of engagement with the work further greatly facilitates the turning or rolls without undue frictional rubbing since the feather is more lightly gripped at its outer edge. lower feed roll is such as to insure against liability of the edge of the roll to dig into the face of the sole when the abruptly bent portion at the unction of the shank and fore- The an le of bevel of the face of the part is reached. Thus, injury to the stock is prevented and engagement secured between the sole and the lower feed roll throughout the entire width of the latter during the period of operation in the vicinity of the break between theshanlr and forepart of the sole, thus preventing the advance'of the sole from being retarded atlthis point.

In order that the work shall be yieldingly gripped between the feed rolls and to, enable the rolls to be separated to permit insertion and removal of the work, the lower feed roll shaft 32 is slidably mounted in its bearingsin the head 18 and is normally urged upwardly by means of a spring 60 1) secured ate-its upper end to a portion of. the head 18 and'at its lower end to the downwardly extending arm of a lever 62 which is maintained in sup porting engagement with the lower end of-the feed roll shaft 32 by the action of the spring 60. The lever 62 is pivoted to thehead 18 at 64 and the upper arm of the lever carries an adjustable, stop screw 66 arranged to bear against a portion of the head 18 to limitthe upward sliding movement of the shaft 32.

To prevent contact of the feed rolls with one another when no work is present between them, adjustment of the stop screw 66 may be made for the purpose of varying the limit of approach of the feed rolls. The lower end of the shaft 32 protrudes below its bearing in the head 18 and is encircled by a spring 68 which'is compressed between the shaft bearing and a collar or washer 70 carried by the shaft. The spring 68 tends to urge the shaft 32 downwardly against the upward pull of the spring 60; but being weaker than the latter spring 1s effective to separate the feed rolls i only when the lever 62 is swung downwardly by means such as afoot treadle, not shown,

which may be connected through a treadle rod 72 with the lever 62. On account of the inclination of the lower feed roll shaft- 32 the shaft does not slide downwardly within its bearings readily in response to downward pressure verticallyv directed against the lower feed roll and consequently said feed roll is supported with suffic1ent rlgidity to sustain the work against the action of the lip turning wheel but will yield if'unusual resistance is i the lip of the sole.

1 length of the lip. To this end, the lip' turning wheel is provided with a plurality of beating and wiping rolls 76 which. are mounted between the marginal portions of two disks 78 and 80'and the rolls are retained in place by means of pins 82 carried by said disks. As

. shown, the disk 7 8 is formed with a hub 84 which is fixed on the shaft 52 while the disk 80 is provided with a hub 86 which is fixed upon the hub 84 of the other disk. The disks 78 an d 80 are held apart by means of a spacing collar 88 which encircles the hub 84. The pins 82 extend from one disk to the other in parallel relation to the shaft 52 and are secured at their ends to the respective disks.

In order that the rolls shall exert a yielding beating and wipingaction upon the'lip they are axially bored to provide central apertures of greater diameter than the diameter of the pins 82. The rolls are thus loosely mounted .uponthe pins 82 and as aresult when the lip turning wheel is in rotation the rolls 7 6 will normally be maintainedby centrifugalforce at the outermost limits of radialrnovement determined by the pins 82. The feed rolls 10 and 12 are'so located vertically with respect to the lip turning wheel .as to position the work with respect to the path of'movement of the rolls 76 so that as said rolls successively engage the lip they will yield inwardly toward the axis of the lip turning wheel, and will be yieldingly urged outwardly by centrifugal force as they move transversely of the lip, thus insuring yielding wiping engagement of each roll with the lip throughout the full width of the latter.

provision is made, in the illustrated machine} for enabling the lip turning rolls to move endwise in the direction of work feed while they are in wiping engagement with the work. This is accomplished by spacing apart the'disks 7 8 and a distance greater than the width of the rolls 7 6 and thus providing for a limited amount of axial movement of each roll whilev it is in engagement with the lip. Normally the rolls are maintained in engagement with the disk 80 which is in advance of the. disk 78 in the line of feed, by means of light spring fingers 90 which are formed by making a series of radial cuts or notches in a spring disk 92 whichis centrally apertured' to encircle the hub 84: of the disk 78 and is conveniently clamped between said disk and the collar 88. The outer ends of the fingers 90 are notched to enable the fingers to straddle the pins 82 so that they will bear against the cndfaces of the rolls 76. By reason of the above-described construction, as plainly shown in Fig. 4 each roll 76 is free to move axially, or in the direction of i work feed, against the force of the light springfingers 90 while in actual engagement withthe work. Inasmuch. therefore, as the lip turning wheel rotates in a plane at right angles to the length of the lip, the above described construction and arrangement of the lip turning rolls enables themto wipe across the lip ina direction at right angles to the length ofthe lip, notwithstanding the continuous advance of the work. Intliis way the lip is turned in a most efficient manner in simulation of well-known hand methods of lip turning which have alwaysvgivenmost satisfactory results. By enabling the lip turning rolls to move endwise with the work Thus each roll 7 6 initially engages the lip at the base there-- as the latter advances frictional rubbing of the lip lengthwise across the rolls is avoided and there is no resulting objectionable drag imposed upon the work. As each roll leaves the lip the respective spring finger 90 restores the roll to the vertical plane of the other rolls so that it is ready to move/axially with the work when it is again brought into engagement therewith.

On account of the spaced relation of the disks 78 and 80, which permits the abovedescribed axial movement'of'the rolls 76 to take place, the rolls 7 6 are also rendered capable of tilting or angular adjustment upon the pins 82, thus enabling the rolls to tilt as may berequired to accommodate themselves to inequalities of the lip. Normally, however, the rolls are maintained in the vertically alined untilted positions shown in Fig. 2 by the action of the'spring fingers'90. As shown in Fig. 1, the lip turning wheel, as well as the driving gears 5a and 56 and a portion of the upper feed wheel 10 are enclosed within and protected by a two-part hollow casing 98, the casing being open at its lower portion to permit the lip turning whee] and the upper feed roll to operate on the work.

To enable the lip turning .rolls 76 properly to engage the lip to turn it over against the face of the sole the lip is preliminarily raised by the action of the stationary plow 14 which is located just in advance of the lip turning wheel in the line of feed. As shown in Fig. 2, the plow 14 is formed with an upwardly extending shank portion 100 which is received with provision for vertical .ad justment within a socket formed upon the ex terior of the casing 98. 1

v Figs. 7 and 8 illustrate an alternative form of the invention in which a lip' turning wheel of modified construction is employed. As shown in these figures the lip turning wheel, which is indicated at 104, is in the form of a single disk or wvheel having its periphery notched to provide a plurality of lip turning teeth or projections 106 each of which is provided with a curved lip-engaging face. in-

asmuch as no yielding action is-provided for in the construct-ion 0f the lip turning wheel 10% the wheel itself is yieldingly mounted so that it will yield bodily upward as the teeth 106 successively engage the lip and will be yieldingly pressed downward as said teeth wipe across the face of the lip, thereby insuring wiping contact of each tooth throughout the full width of the lip as the tooth moves across the lip. To this end the shaft which carries the lip turning wheel 104 is journalcd' in a casing member 108 which is pivotally mount ed upon the shaft 46 and is acted upon by a spring 110 which tends to, swing the casing 108 and consequently the'lip turning wheel,

downwardly about the axis of the shaft 46 to an extent limited by a stop inthe form of a nut 112 threaded upon a belt-114i whieh is pivotally mounted at 116 and extends through the spring 110 and through a lug 1-18 on the casing member 108, the stop 112 coacting with the lug 118 to perform its limiting function. The nut 112 may be turned to adjust the normal vertical relation of the lip turning wheel to the lower feed rolls. As shown in Fig. 8 the lip turning wheel 10415 mounted with provision for a limited amount of axial movement upon its supporting shaft against the action of a coiledspring 120 which encircles said shaft, This construction tends to prevent injury to the work such as might occur when operating upon a lip'having inequalities therein, the feed wheel yielding in the direction of feed to facilitate passage of the wheel over said portions of the lip. If de sired a presser foot, such as that shown at 122 in Fig. 8, may be employedfor engaging the lip after it has been acted upon by the lip turning wheel to set the lip in its final position. A presser foot'of this character is particularly useful also for the purpose of preventing undue puckering or buckling of the tact therewith. The work feeding means has been arranged to permit the'sole to be turned readily as the more or less sharply curved por tions of its margins are being operated upon; and to operate effectively upon molded soles, such forexample as those having so-called cottage-roof shanks, without tending to distort or flatten out the molded contour of the sole, and more especially to avoid breaking down the abrupt bend between the shank and forepart of molded soles of this general type.
